Twist Drill — Type N short, Ø 8.1 mm, 135° point angle, Bright finished, Short execution, DIN 338, HSS‑G (MetavCUT)

A Twist Drill (Type N) designed for precise metal drilling on drilling machines and stationary machine tools.

• Short design for higher stability and precision
• HSS‑G fully ground for sharp, clean holes
• 135° point angle suited for hard materials like stainless steel
• Conforms to DIN 338 for short twist drills
• Short overall length reduces vibration and deflection

Greater Stability and Faster Drilling for Metalwork

The short design of this Twist Drill delivers increased Stability and reduced deflection when working with hard materials. Shorter overhang from the Chuck improves concentricity and lowers the risk of bending, which directly raises hole accuracy. In many industrial applications the HSS‑G ground geometry achieves up to 40% faster drilling and requires 50% less feed force compared with conventional HSS drills, so productivity improves while Operator fatigue decreases.

Precise Tip Geometry for Tough Materials

A 135° point angle optimises entry into hard and abrasion‑resistant metals by reducing the initial bite and spreading heat. For less experienced users: the point angle is the cone at the Drill Tip that influences how quickly the tool penetrates and how well it centres. With Type N normal spiral geometry this tool balances cutting speed and chip evacuation, making it particularly effective for Stainless Steel, Cast Iron and Alloyed Steels.

Engineered Finish and Compliance for Reliable Results

The fully ground flute and land geometry (HSS‑G) produce very sharp cutting edges and excellent Runout accuracy, yielding cleaner holes and longer life under correct conditions. The product conforms to DIN 338, which classifies short Twist Drills with cylindrical shanks and specifies manufacturing tolerances and execution variants. This standardisation supports reproducible setup and interchangeability in workshop environments.

Recommended Use and Machine Compatibility

Designed primarily for machining metal, this Twist Drill suits both stationary machine tools and drilling machines; it is most effective when used with appropriate cutting speeds, coolant and steady clamping. For hand‑held Drilling Machines take care with feed and torque limits because fully ground HSS drills can be more brittle than rolled variants; cooling and moderate speeds extend tool life. Typical applications include holes in unalloyed and alloyed steels, castings, sintered parts and hard plastics.

Material Care and Maintenance Tips

The HSS‑G material benefits from correct machining parameters: use steady coolant/lubrication for deep or high‑speed holes, and avoid excessive pecking without coolant to prevent heat build‑up. The fully ground geometry makes re‑sharpening straightforward for experienced toolmakers, while maintaining concentricity is essential to prevent premature breakage. For best performance, inspect the Twist Drill for wear and micro‑chipping before each critical operation.

FAQ

What is the MetavCUT Twist Drill used for?
The MetavCUT Twist Drill (Type N) is primarily used for drilling metal; it excels in producing precise holes in alloyed and unalloyed steels, cast components and hard plastics when used on drilling machines or stationary machine tools.

Can the MetavCUT Twist Drill be used in a hand drill?
The MetavCUT Twist Drill can be used in a hand drilling machine with caution; due to its short, fully ground HSS design it performs best in well‑supported setups and benefits from controlled feed, cooling and firm clamping to avoid breakage.

For what is a Twist Drill used?
Twist Drills are mainly applied to machining high‑strength materials and larger diameters; their form is easy to re‑grind and they withstand greater loads, making them suitable for demanding metalwork.

Which three drill types exist?
There are three main drill types: Metal drills, Wood drills and Stone/Concrete drills.

Why are Twist Drills sharpened (pointed)?
Sharpening reduces the cross‑cut at the tip, which lowers friction and the required feed force while improving the drill’s centring in the workpiece.

Can you drill wood with a Twist Drill?
Metal drills can be used in wood, but they offer poorer guidance and a less clean finish; however, they are easier to resharpen and have lower self‑feed tendencies.

At which drilling depths is the Twist Drill most commonly used?
Solid drilling is commonly executed with Twist Drills; they are most frequently the tool of choice for diameters up to 20 mm and drilling depths up to 100 mm.

Is HSS or HSSE better?
The general belief that HSSE is always superior to HSS is incorrect; choice should be based on the specific working conditions and whether those conditions justify the higher cost of HSSE.
